I want a true ip_id from the kernel and this id will not be used by any other packet.
Although there are few chances that our randomly chosen ip_id collides with the other packet's ip_id generated by kernel, I don't want this possibility to happen.
So is there any method to get a true ip_id from the kernel?
I want this ip_id to do my own fragmentation on a packet.
Thanks!
